Great to meet you at WCNA this weekend – and now I'm extra stoked for NYC next year! :) Hope you had a good conference experience and till next WCNA, see you around the wikis! Accedietalk to me18:58, 8 October 2024 (UTC)
You are invited to Wikidata Day in New York City at Pratt Institute School of Information in Manhattan, in celebration of Wikidata's 12th birthday. This event, held by our chapter in collaboration with Pratt and Girls Who Code, will be our third annual celebration of Wikidata Day. It will feature spotlight sessions, lightning talks, and the customary Wiki-cake, while those unable to attend in person will be able to watch a livestream.
All attendees are subject to Wikimedia NYC's Code of Conduct.
Even WP:CSD#G1 is inapplicable if there is any way the content can be reasonably understood, so I would have declined then as well, but merely for being out of scope of the speedy deletion criteria. However, I have no prejudice against a nomination at redirects for discussion; I suggest you bring concerns about neutrality and verifiability to a discussion there. Complex/Rational18:50, 10 October 2024 (UTC)
There are 4 deletions on the page of Banu Qurayza, all of which correspond to major edits. The reasons listed on the deletions is that they violate copywrite. The page itself is implicated in an ANI outcome (Incident archive 1159: Kaalakaa on Islam-related topics) where a consensus of uninvolved found that the user @Kaalakaa maintained a collection of NPOV abused pages on Islam related topics, including this page.
I would like to request a copy of the deleted content (3 most recent deletions), all of which were found violating RD1: Copywrite. I would like to salvage the knowledge and assess if portions of it remain relevant. If so, remedy it of its violation to be reintroduced, as long as its citations are of acceptable standard.
@Bro The Man: I cannot provide or reinstate content that was deleted as copyright infringement. Additionally, the additions of infringing content were immediately reverted, so they had no long-term impact on the overall accuracy and neutrality.
The deletion log entries include some of the sources from which material was copied, though, and you are free to assess the original sources for relevance and write fresh content in your own words. However, I am not familiar enough with the subject matter to point you to the best available sources. I see that you also started a thread on the article's talk page and I hope that you find assistance there. Thanks, Complex/Rational16:33, 16 October 2024 (UTC)
So it was just blocks of copy-pastes? If that's so, then that's useless, lmao. Please, let me know if i understood you correctly. Bro The Man (talk) 18:27, 16 October 2024 (UTC)
I haven't checked it thoroughly, but in general, copyright infringement refers to improper verbatim copy-and-paste or close paraphrasing. So yes, you'll find essentially the same material in the original sources as you would in the deleted version. Complex/Rational19:59, 16 October 2024 (UTC)
Invitation to participate in a research
Hello,
The Wikimedia Foundation is conducting a survey of Wikipedians to better understand what draws administrators to contribute to Wikipedia, and what affects administrator retention. We will use this research to improve experiences for Wikipedians, and address common problems and needs. We have identified you as a good candidate for this research, and would greatly appreciate your participation in this anonymous survey.
You do not have to be an Administrator to participate.
The survey should take around 10-15 minutes to complete. You may read more about the study on its Meta page and view its privacy statement .
Please find our contact on the project Meta page if you have any questions or concerns.
Mass deletions done with the Nuke tool now have the 'Nuke' tag. This change will make reviewing and analyzing deletions performed with the tool easier. T366068
@Double sharp: Thanks for sharing the exciting news! I suppose the new isotopes could be added, but I'm not sure that WP:CALC permits computing half-lives in the absence of aggregated data and complete analysis... so a more detailed update will likely have to wait. Complex/Rational15:34, 2 November 2024 (UTC)
Yeah, I've confined myself to just adding their existence. (Well, I guess their colour in the Table of nuclides can be handwaved as obvious; computing the detailed half-life is too much, but it's too obvious that it must be <1 d. :D) Double sharp (talk) 15:34, 2 November 2024 (UTC)
Wow, one more nuclide with Z:N = 2:3 found, whoopee! Discovering 295Og in the future would complete this huge family from 5He to 295Og, spanning from the beginning to the end of the periodic table. 129.104.65.2 (talk) 00:06, 3 November 2024 (UTC)
I'm looking forward to synthesis of 295,296Og with 250,251,252Cf + 48Ca and 248Cm + 50Ti. Besides that, I'm also hoping for the discovery of 293Og to clean up Ninov's mess completely. Nucleus hydro elemon (talk) 06:59, 3 November 2024 (UTC)
@Nucleus hydro elemon: You know what else I want? A sustained search for the pxn channel from 248Cm+48Ca to get heavier Mc isotopes (to see if they really electron-capture their way to the middle of the island), plus sustained looks at 242Cm+48Ca to get even lighter Lv isotopes. And the odd-Z cases too, but you already know that. I guess the dream of using 250Cm will have to languish in limbo for a long while. :)
248Cm(48Ca,p3n)292Mc has extremely bad cross section (12 fb).[1] I found nothing about 242Cm+48Ca, probably because 242Cm is too unstable, even more unstable than 249Bk. I think 238-240Pu+50Ti makes more sense, but there exists only a prediction 43 years ago, which states 238Pu(48Ca,4n)284Lv has a cross section of a few pb.[2]
I have a complicated feeling towards nuclides at the island of stability, especially if they have a half-life in centuries or millennia. After formed from the EC chain, the atom will outlive any SHE researcher, so no one can know its decay properties. It might be hard to detect the existence of this long-lived atom. I don't think chemistry can be done, as chemistry done in a single atom relies on its radioactive decay, which this long-lived atom will never do in a reasonable timeframe. Nucleus hydro elemon (talk) 08:06, 3 November 2024 (UTC)
@Nucleus hydro elemon: True, but I guess an ER that has no plausible SF event following it would be quite a sign that the island's been reached at least. And yeah, 242Cm is perhaps a bit ambitious, but at least 243Cm has a half-life of a few decades and will get us most of the way. :) Double sharp (talk) 08:11, 3 November 2024 (UTC)
Found a prediction about 243Cm+46,48Ca.[3] It also predicts 245Cm+46Ca, but this reaction is worse than 243Cm+48Ca in all channels, so I ignored it. Cross sections are square bracketed and in pb.
The funny thing is that 244Pu+50Ti (0.44+0.58 −0.28 pb) seems to have a larger cross-section than 208Pb+70Zn (0.078+0.179 −0.065 pb). If not for the serendipitous 294Og atom produced in 2012 during a Ts campaign (when the 249Bk target had significantly decayed), I wonder if it might've been tried last decade, as it would both confirm 118 by producing its daughter 290Lv, and provide useful experience with 50Ti back when people were already thinking about 119 and 120. Though looking at the trend, it seems distressingly plausible that current technology levels have simply made 119 and 120 go from "it's not gonna happen" to "sure, if you're willing to spend years and years like RIKEN did with 113"... Double sharp (talk) 08:14, 3 November 2024 (UTC)
The source I added to moscovium also discusses αxn channels, and suggests they may be more favorable to produce heavier Mc isotopes from 249Bk and 48Ca. On the other side, some of the neutron deficient even–even isotopes may have very short SF half-lives (predicted by several sources and supported by observations of 284Fl, 282Cn, and now 280Cn), so they may not be readily detectable even with cross sections within experimental detection limits. Complex/Rational15:08, 3 November 2024 (UTC)
I'm kind of wondering how we should handle the successful pxn – it doesn't fit quite well with how the superheavy "isotopes of X" pages are currently handled. Well, what a happy problem to have! Double sharp (talk) 15:53, 2 November 2024 (UTC)

doi:10.1142/S0218301320500536 predicts among 284-308Uue, 296,300,302Uue have a half-life of >100 μs. (297,308Uue may reach this bar or not depends on prediction used) Only 296Uue is a reasonable long-lived isotope to be synthesized among them. 297Uue requires either 2n channel, 250Cm, or einsteinium, while even heavier isotopes are more unlikely to produce.
On the other hand, I found lighter isotopes 292,293Uue interesting because the whole decay chain is unknown. However, their predicted half-lives of ~30 μs is troublesome. Nucleus hydro elemon (talk) 08:22, 2 November 2024 (UTC)
It does indeed seem that even-Z SHEs have been getting much of the attention lately. Meanwhile, the gap between cold and hot fusion persists for odd-Z elements, and Mt and Rg each have one isotope that has been directly synthesized... decades ago. Complex/Rational16:32, 2 November 2024 (UTC)
Since you mention 266Mt from 1982: Peter Armbruster and Gottfried Münzenberg both died this year. :( (Sigurd Hofmann died in 2022.) Double sharp (talk) 16:36, 2 November 2024 (UTC)
I guess the even-Z gap gets studied more because it looks like 120 is going to be easier than 119. Maybe once 120 is discovered, we'll see a renaissance of interest in the odd ones. Double sharp (talk) 16:43, 2 November 2024 (UTC)
@Double sharp: I stumbled upon this, which mentions a proposed search for 276Rg and 272Mt (along with 250Lr and 254Db) – though neither a reaction nor an experimental timeframe are described. If year 1 was 2020, we're in year 5, and I haven't found anything more recent, so I wonder what became of this.
Well, the 50Ti agenda happened quite similarly to the plan of those slides, with the 244Pu+50Ti reaction having succeeded. Perhaps the other things happened, or perhaps it was decided that going for 120 was more exciting. Yeah, that's kind of a non-answer. ;) Double sharp (talk) 04:29, 11 November 2024 (UTC)
November 22 + 26: Free Culture Friday and Wikicurious photo event!
You are invited to Foundation and Friends' Free Culture Friday at Prime Produce on Friday, November 22. This event will feature a reception with Wikimedia Foundation staff in the afternoon, followed by a more informal salon and game night, utilizing Prime Produce's vast collection of board games. No experience of anything at all is required. All are welcome!
You are also invited to Wikicurious: Capturing the Moment, the third event of the beginner-focused Wikicurious series, at Jefferson Market Library on Tuesday, November 26, in collaboration with WikiPortraits and AfroCROWD. All are welcome to attend, especially those interested in photography or contributing to Wikimedia Commons. We will explore the art of capturing the moment through photography and learn the basics of Wikimedia Commons, and (weather-permitting) we are also planning a photo walk, so bring your camera (or use your smartphone)!
I recently invited you to take a survey about administration on Wikipedia. If you haven’t yet had a chance, there is still time to participate– we’d truly appreciate your feedback. The survey is anonymous and should take about 10-15 minutes to complete. You may read more about the study on its Meta page and view its privacy statement.
Interesting :) Its predicted alpha half-life is 1.3 ms (doi:10.1016/j.physletb.2022.137569), which is consistent with the experimental half-life >1 ms. The prediction also predicts its double alpha half-life will be 537 ms.
Looking forward to the publication and additional discoveries. Also hoping that some of the missing or poorly-studied isotopes described in NUBASE2020 are the subject of future work. Complex/Rational01:57, 11 November 2024 (UTC)
By the way, 222Rn is also listed in the list of nuclides predicted with shortest double alpha half-lives. With a predicted half-life of 3 years, this decay mode is observable. Unfortunately, I'm not sure is there a way to separate 222Rn→218Po→214Pb and direct 222Rn→214Pb. Nucleus hydro elemon (talk) 11:15, 9 November 2024 (UTC)
If I'm understanding correctly, there should be a measurable time delay if 218Po is produced as an intermediate product, whereas double alpha decay would feature both alphas emitted simultaneously. I haven't read many articles about this, but I'd instead think it would be harder to distinguish double alpha decay from 8Be cluster emission. Complex/Rational01:57, 11 November 2024 (UTC)
According to the predictions, double alpha decays (if we have method to distinguish them from two separate alpha decays) of 148Sm and 152Gd are clearly observable! (Perhaps also 150Gd and 154Dy, if these two nuclides are available). 129.104.241.5 (talk) 23:12, 13 November 2024 (UTC)

Hello! Voting in the 2024 Arbitration Committee elections is now open until 23:59 (UTC) on Monday, 2 December 2024. All eligible users are allowed to vote. Users with alternate accounts may only vote once.
The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to impose binding solutions to disputes between editors, primarily for serious conduct disputes the community has been unable to resolve. This includes the authority to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail.
@Bearian: Nice meeting you as well. Feel free to drop by here (although there are still some math articles I don't dare touch), and I look forward to seeing you at future meetups. Complex/Rational23:14, 22 November 2024 (UTC)
Following an RFC, the policy on restoration of adminship has been updated. All former administrators may now only regain the tools following a request at the Wikipedia:Bureaucrats' noticeboard within 5 years of their most recent admin action. Previously this applied only to administrators deysopped for inactivity.
Following a request for comment, a new speedy deletion criterion, T5, has been enacted. This applies to template subpages that are no longer used.
Hello, and welcome to the December newsletter, a quarterly digest of Guild activities since September. If you no longer want this newsletter, you can unsubscribe at any time; see below. If you'd like to be notified of upcoming drives and blitzes, and other GOCE activities, the best method is to add our announcements box to your watchlist.
Election news: The Guild's coordinators play an important role in the WikiProject, making sure nearly everything runs smoothly and on time. Editors in good standing (unblocked and without sanctions) are invited to nominate themselves or another editor to be a Guild coordinator (with their permission, of course) until 23:59 on 15 December (UTC). The voting phase begins at 00:01 on 16 December and runs until 23:59 on 31 December. Questions may be asked of candidates at any stage in the process. Elected coordinators will serve a six-month term from 1 January through 30 June.
Drive: In our September Backlog Elimination Drive, 67 editors signed up, 39 completed at least one copy edit, and between them they edited 682,696 words comprising 507 articles. Barnstars awarded are here.
Blitz: The October Copy Editing Blitz saw 16 editors sign-up, 15 of whom completed at least one copy edit. They edited 76,776 words comprising 35 articles. Barnstars awarded are here.
Drive: In our November Backlog Elimination Drive, 432,320 words in 151 articles were copy edited. Of the 54 users who signed up, 33 copy edited at least one article. Barnstars awarded are posted here.
Blitz: The December Blitz will begin at 00:00 on 15 December (UTC) and will end on 21 December at 23:59. Sign up here. Barnstars awarded will be posted here.
Progress report: As of 22:12, 7 December 2024 (UTC), GOCE copy editors have completed 333 requests since 1 January, and the backlog of tagged articles stands at 2,401 articles.
Thank you all again for your participation; we wouldn't be able to achieve what we have without you! Cheers from your GOCE coordinators, Dhtwiki, Miniapolis, Mox Eden and Wracking.
To stop receiving GOCE newsletters, please remove your name from our mailing list.
Exciting news! I think Lv is doable, but I don't think chemistry of Ts can be done if the berkelium target needed for Ts production is so hard to obtain. :(
By the way, is there any new predictions about Ts? After At is predicted to be a metal with density ~9 g/cm3, the "semimetallic" and low density of ~7 g/cm3 at the infobox of Ts looks outdated. Nucleus hydro elemon (talk) 13:19, 27 November 2024 (UTC)
Interesting. And it looks like Mt, Ds, and Rg will continue to be ignored, even though at least Rg is arguably more accessible than Ts (easier synthesis and longer half-lives - at least of the granddaughters of Mc). Complex/Rational14:30, 27 November 2024 (UTC)
The reasoning given by their articles is there are no volatile compounds of Mt, Ds, Rg without fluorine. If we somehow managed to do SHE fluorine chemistry, then the volatile fluorides DbF5, SgF5,6, BhF5,6,7 and HsF5,6,(7,8)? can be studied. Nucleus hydro elemon (talk) 14:49, 27 November 2024 (UTC)
Current detectors are not sensitive towards EC, so any way that could detect it looks good. I'll look forward to 287,290Fl→Nh and 268,270Db→Rf that solves unconfirmed nuclei, but I couldn't figure out a chemical way to separate them. (Can it detect a less volatile daughter?) :\
A request for comment is open to discuss whether admins should be advised to warn users rather than issue no-warning blocks to those who have posted promotional content outside of article space.
Technical news
The Nuke feature also now provides links to the userpage of the user whose pages were deleted, and to the pages which were not selected for deletion, after page deletions are queued. This enables easier follow-up admin-actions.
The special focus this year will be the launch of our "400 Neighborhoods" campaign for the city's 400th anniversary and WikiProject New York City/400 Task Force.
We'll also have a lightning talks session and you're invited to sign up for one, though space is somewhat limited.
Administrators can now nuke pages created by a user or IP address from the last 90 days, up from the initial 30 days. T380846
A 'Recreated' tag will now be added to pages that were created with the same title as a page which was previously deleted and it can be used as a filter in Special:RecentChanges and Special:NewPages. T56145
